[Prior art]
2. Description of the Related Art Conventionally, various techniques related to architectural fittings have been devised and provided.
The present inventor has also proposed and put to practical use a number of architectural fittings as a leading expert in the development of architectural fittings.
However, most of the conventional joint fittings for construction are related to shaft joints such as pillars and beams, torches, foundations, etc., and as joint fittings used for roof frames, the present inventor's Japanese Patent Publication 8- Only a few things can be seen, such as those related to 33041. In particular, there were almost no joint fittings used for the frame of the dormitory roof.
[0003]
[Problems to be solved by the invention]
As described above, the roof, in particular, the dormitory roof, has not been put to practical use, and has been framed by a conventional construction method. FIG. 18 is a partially omitted perspective view showing a hut assembly of a dormitory roof according to a conventional method of a Western style hut.
[0004]
In the conventional construction method shown in the figure, a purlin 101, two corner joints 102 (one is omitted), two flat joints 103, and one wife joints are formed above the corner bundle 100. 104 is joined by a joint.
For this reason, the joint processing for each joint becomes complicated, requiring a lot of work, and at least five joints must be processed on the outer circumference of the same height of one corner true bundle. The strength was not enough.
[0005]
Also, when building the roof, the corner bundles 100 are centered, the ends of a plurality of joints (two corner joints 102 and three flat / wife joints 103, 104) are joined, and purlin 101 was performed.
In addition, since this joining work needs to be performed at a construction site where the scaffolding is high at a high place, the work efficiency is low and there is a problem in terms of safety.
[0006]
In order to avoid complicated processing work and joining work at high places, a method of assembling and joining the entire roof in advance and then placing it on the building is also employed.
However, in this case, a work space for assembling and joining the entire roof in advance is required at the construction site, and a large crane for placing the completed roof on the building is required.

[0013]
Moreover, this invention is set as the structure which formed the flange in the bottom part of the said metal fitting main body.
In this way, the end of the splint member can be placed on the top surface of the flange, and the weight of the splint member can be supported by the flange, and as a result, the joining strength of the splint member to the metal fitting body is increased. be able to.
[0014]
Further, in the present invention, the planar shape of the pressing member is a shape that covers the upper opening of the metal fitting body, and has a through hole of the shaft bolt at the center.
If it does in this way, the structure of a pressing member can be simplified and a joining plate can be latched reliably.
[0015]
Moreover, this invention is set as the structure which the said slit has an opening part in the surrounding wall upper part of the said metal fitting main body, and formed the inclination for the guide of a joining plate in this opening part.
If it does in this way, a joining plate can be easily latched to a metal fitting main body, and it can improve worker's safety especially in the construction site where a scaffold is unstable at a high place.

[0025]
In the same figure, the joining plate 2a for joining the palms and the joining plate 2b for joining blocks are made of a plate-like member such as a steel plate, and at least the latching portion 20 latched by the slit 12 of the metal fitting body 1 and the joining palm and the purlin. It has bolt holes for fixing with bolts and nuts.
Here, an inclined portion 22 is formed on the opposite side of the locking portion 20 from the bolt hole 21, so that the joining plates 2 a and 2 b can be easily locked to the slit 12.
[0026]
The joint plate 2a for jointing has a shape having a lower hypotenuse 23 having the same inclination as the slope of the corner joint (corner slope) and an upper hypotenuse 24 having the same inclination as the slope of the flat joint and the wife joint (flat slope). .
Further, the jointing plate 2a for the palm is provided with four bolt holes 21 and 21a, 21 and 21a substantially parallel to the lower oblique side 23, and four bolt holes 21 and 21b substantially parallel to the upper oblique side 24. , 21 and 21b are drilled. Of these bolt holes, the two bolt holes 21 and 21 on the center side are shared.
[0027]
In this way, it is possible to share the joint plate for corner joints and flat joints with different slopes (the wife joint is the same slope as the flat joints), and the manufacturing cost of the joint plate can be reduced. Can do. Also, workability can be improved in the assembly work.
[0028]
The purlin joining plate 2b has a structure having a rectangular portion in which four bolt holes 21 are formed.
Here, the distance “L” from the locking portion 20 to the upper surface may be constant for the joining plates to be used, for example, the jointing joining plate 2a and the purlin joining plate 2b, and will be described later. By bringing the pressing member into contact with these upper surfaces, the engagement state of the joining plate can be easily maintained.
[0029]
Although not shown in the figure, the palms and purlins have through holes formed at positions corresponding to the bolt holes, and the bolts are inserted into the through holes and the bolt holes, and the nuts are screwed together to join. The plate can be easily fixed to the purlins.
Further, the shape of the joining plate and the position and quantity of the bolt hole are examples when the splint member is a palm and purlin, and has various shapes and positions and quantities of the bolt hole according to the splint member. A joining plate can be used.
[0030]
Next, the structure of the fixing means for the architectural fitting according to the first embodiment of the present invention will be described.
[Structure of fixing means]
FIG. 4: has shown the schematic front view for demonstrating the structure of the fixing means of the joining metal fitting for construction of 1st embodiment which concerns on this invention.
In the figure, the fixing means comprises a shaft member 30a, a shaft bolt 32 made up of all screws, and a nut 33.
Here, the shaft member 30a has a structure in which a female screw 30c is processed in the upper part and a pin hole 30b is formed in the lower part.
[0031]
Further, a square tenon 41 is formed at the upper end of the main wood member, and a thick plate member 4 in which a tenon hole 42 fitted to the square tenon 41 is formed is provided on the lower surface of the flange 11. If it does in this way, since the flange 11 is joined to the main wood member at an angle determined by the fitting of the square mortise 41 and the mortise hole 42, it is possible to increase the joining strength in the circumferential direction and to rotate the metal fitting body. Deviation in the direction can be effectively prevented.
[0032]
In the fixing means having the above configuration, the shaft member 30a is embedded in the main tree member, and although not shown, the pin 31 described later is fixed to the main tree member by being inserted into the pin hole 30b. The
Then, the shaft bolt 32 is inserted into the shaft bolt hole 15 of the flange 11 placed on the upper portion of the main wood member, and is screwed with the female screw 30c. Further, the nut 33 is screwed with the shaft bolt 32. The flange 11 is fixed to the main wood member.
[0033]
The fixing means is a technique proposed by the present inventor in Japanese Patent Application No. 8-114161, and is not limited to the above configuration. For example, a male screw is processed instead of a female screw, and a shaft It is good also as a structure which uses a nut instead of a volt | bolt.
[0034]
According to the above-described metal fitting, the bonding plate, and the architectural fitting having the fixing means, it is only necessary to provide a groove for pushing the bonding plate into the splint member, so that it is not necessary to perform complicated joint processing. The processing time required for the mouth processing can be shortened, and the joining strength of the splint member can be increased.
[0035]
Note that the splint member is a wooden member used for purlins, joints, and the like, and is usually composed of an interposer and two standard members joined so as to sandwich the interposer.
Here, it is preferable that the thickness of the joining plate is substantially the same as the thickness of the intermediate plate, and in this way, the bonding plate can be pushed into the later-described intermediate plate space. Can be further shortened.
[0036]
Next, a usage example using the above-described joint fitting for building will be described with reference to the drawings.
First, as shown in FIG. 5, for example, as shown in FIG. 5, a corner bundle 70, a purlin 71, and a corner joint 72 with a bracket main body 1 fixed to the upper portion of the roof of a western style hut are provided by the architectural fitting according to the invention. , Flat joint 73 and wife joint 74 may be joined, and this use example will be described.
[0037]
[Example of use]
FIG. 6: has shown the schematic plan view of the principal part for demonstrating the usage example of the joint fitting for construction of 1st embodiment in this invention.
In this figure, the metal fitting body 1 is not shown, but is fixed to the upper part of the corner true bundle 70 which is a main tree member, and the purlin junction plate 2b and the palm joint plate 2a are purlin members which are splint members, respectively. 71, a corner joint 72, a flat joint 73, and a wife joint 74. The bolts 25 and nuts are fixed to the intervening space at the ends. Furthermore, the splint member 2b and the palm joint plate 2a are engaged with the metal fitting body 1 so that the splint member is joined to the main wood member.
[0038]
Then, it demonstrates with reference to sectional drawing of the usage example of the joining metal fitting for construction.
FIG. 7: has shown sectional drawing in the CC line of FIG. 6 which showed the usage example of the joining metal fitting for construction.
In the figure, the metal fitting body 1 is fixed to the corner true bundle 70 by the fixing means 3. Specifically, a shaft bolt 32 consisting of all screws is embedded in the corner true bundle 70 and fixed by the pin 31. The bracket body 1 is screwed onto the shaft member 30 a while being inserted into the shaft bolt hole 15 of the metal fitting body 1, and the nut 33 is fastened to the shaft bolt 32, so that the metal fitting body 1 is attached to the upper surface of the corner true bundle 70. Fixed. In order to prevent the nut 33 from loosening, a double nut is tightened.
[0039]
Here, it is preferable that a square tenon 41 is formed in the upper portion of the corner true bundle 70, and the thick plate member 4 having a tenon hole 42 fitted to the square tenon 41 is used on the bottom side of the metal fitting body 1 with a bolt 40. In this case, the metal fitting body 1 is joined to the main wood member at an angle determined by the mortise 42, so that the joining strength is improved and the metal fitting body 1 is prevented from turning around. can do.
[0040]
The purlin 71 is joined to the metal fitting body 1 by the locking portion 22 of the purlin joining plate 2 b fixed to the end portion by the bolt 25 being engaged with the slit 12 of the metal fitting main body 1. However, strictly speaking, the joining plate 2b is movable upward.
For this reason, the joining plate 2b for purlins is good to set it as the structure which the front-end | tip part side by the side of the corner true bundle 70 contact | abuts the presser member 5, and if it does in this way, the joining plate 2b will not remove | deviate easily from the metal fitting body 1 ( It becomes impossible to move in the upward direction, and the locked state is maintained.), And the reliability of joining can be improved.
[0041]
The presser member 5 has a top surface shape that fits inside the cylindrical member 10 (an example of a shape that covers the upper opening of the metal fitting body), and the shaft bolt 32 passes through the center. It is preferable to have a structure having a through hole. By doing so, the through holes of the holding member 5 and the washer 50 are inserted into the shaft bolt 32, and the two nuts 51 are tightened with a double nut so as not to loosen. Can be easily maintained.
[0042]
Further, the fixing structure of the pressing member 5 is simplified by fixing the pressing member 5 by using the shaft bolt 32 used for fixing the metal fitting body 1.
Of course, the same structure can be applied to the joining plate fixed to other splint members.
[0043]
The purlin 71 has a contact portion 71a protruding from the joining plate at the lower end of the tip, and the contact portion 71a is placed on the upper surface of the flange 11 of the metal fitting body 1 and supports the weight of the purlin 71. In this case, it is possible to disperse the external force acting on the slit 12 and the locking portion 22, and it is possible to prevent problems such as deformation of members around the slit 12 due to this external force.
Furthermore, for example, the position of the purlin 71 can be easily finely adjusted by cutting the contact portion 71a.
The same structure can be applied to other splint members, for example, the abutting portion 74a of the wife palm 74.
[0044]
Further, the joint-joining plate 2a is fixed to the tip of the wife joint 74 by bolts 25 and nuts inserted into the bolt holes 21, 21, 21b, 21b.
Here, the jointing plate 2a for the palm joint is firmly fixed to the wife joint 74 because each bolt hole 21, 21, 21b, 21b can effectively exert substantially the same fixing force with respect to the wife joint 74. The
Further, the jointing plate 2a for the palm is fixed so that the upper surface of the upper oblique side 24 forms the same surface as the upper surface of the wife palm 74, and further, the lower surface of the lower oblique side 23 is located inside the lower surface of the wife palm 74, There is no protruding part, and it can join suitably.
[0045]
On the other hand, as shown in FIG. 8, the joint plate 2 a for jointing is fixed to the tip of the corner joint 72 by bolts 25 and nuts inserted into the bolt holes 21, 21, 21 a, 21 a.
Here, the joint plate 2a for jointing is firmly fixed to the corner joint 72 because each bolt hole 21, 21, 21a, 21a can effectively exert substantially the same fixing force to the wife joint 74. The
Further, the joint plate 2a for the palm is fixed so that the lower surface of the lower oblique side 23 forms the same surface as the lower surface of the corner palm 72, and the upper surface of the upper oblique side 24 is located inside the upper surface of the corner joint 72. There is no protruding part, and it can join suitably.
[0046]
In this way, by using the construction fittings in the above-mentioned use examples, the joining work of the purlin 71, the corner joint 72, the flat joint 73, and the wife joint 74 can be easily performed. The work efficiency and safety can be improved even on site.
[0047]
When the building joint fitting of the present invention is used, for example, the following unitized joining method can be adopted.
[0048]
(1) Unit assembly process: In a good working environment such as a factory, the wooden members forming the roof are unitized in advance using the building joint fittings in the usage example, the beam receiving joint shown in FIG. Process.
Here, as an example of the unit, for example, using a fishing hook 78 and a wand 79, a roll joint 75 is joined to a flat joint 73 (see FIG. 9), or a corner joint 76 is joined to a corner joint 72. There is something that was done.
[0049]
(2) Unit joining step: A step of assembling and joining the entire roof by joining the assembled unit to the corner bundle 70.
Here, the united corner joint 72, flat joint 73, and wife joint 74 are joined to the corner bundle 70 by using various joint fittings such as a construction joint and a beam receiving joint according to the present invention.
[0050]
At this time, in the unitized flat joint 73 and wife joint 74, first, the joining plate fixed to the distal end is locked to the metal fitting body 1, and then the ladle 75 is joined to the corner true bundle 70 by the beam receiving fitting. To be joined to the corner true bundle 70.
Further, when assembling the unitized corner joint 72, the corner beam receiving and punching 77 is previously joined to the beam 75 by using a fire metal fitting (not shown) and a reinforcing plate. After that, the united corner joint 72 is first joined to the metal fitting body 1 with the joining plate fixed to the tip, and then the corner hole 76 is coupled to the corner beam receiver 77, Joined to the corner true bundle 70.
[0051]
In this way, the united corner joint 72, flat joint 73, and wife joint 74 first receive the load at one end of each joint when the joining plate is locked to the metal fitting body 1. . As a result, the operator who has lifted this end is released from the lifting operation, and subsequently, this operator can perform the joining operation of the batting 75 and the corner boring 76, so 70 can be efficiently and easily joined. Further, other wooden members, for example, rafters, are sequentially assembled and joined.
In addition, the said beam receiving joining metal fitting is the technique which this inventor proposed in Japanese Patent Application No. 8-114161.
[0052]
In this way, by adopting the architectural bonding method using the above-mentioned architectural fittings, each palm 72, 73, 74 can be easily joined to the corner bundle 70, and the work space at the construction site is saved. Space can be made.
Further, since the unitized splint member can be lifted safely by workers, according to this joining method, the splint member can be safely and quickly attached to the main tree member without arranging a crane or the like. Can be combined.
[0053]
Moreover, this invention is not limited to the said structure, For example, when not using the main-tree part material provided vertically, such as a corner true bundle, it can be set as the structure which uses an axial bridge | bridging etc.
Next, an architectural joint fitting of a second embodiment using a round bridge that is an axial bridge will be described with reference to the drawings.
[0054]

The side plate 242 is formed with a bolt hole 244 for fixing the block 205. If it does in this way, since a connection structure can be simplified, manufacturing cost can be reduced.
[0064]
Further, the side plate 242 is configured to sandwich the block 205 movably, and in this way, when attaching the connecting bolt 223, the block 205 into which the connecting bolt 223 is inserted is attached to the U-shaped plate 204 or attached in advance. Since the connecting bolt 223 is inserted into the block 205 and then the block 205 is rotated, the connecting bolt 223 can be easily inserted into the connecting bolt hole 213 of the round bridge 201. Can be done.
[0065]
The anchor block 202 is attached to the flat palm 73 with a joint dowel 203, a pin 231 and a bolt 232.
The joint dowel 203 is a cylindrical member processed with an internal thread, and has pin holes into which two pins 231 are inserted.
This fixing means is a technique proposed by the present inventor in Japanese Patent Application No. 8-114161, and is not limited to the above configuration. For example, a male screw is processed instead of a female screw, and a bolt It is good also as a structure fixed using a nut instead of.
In addition, the other structures and operations such as the joint-joining plate 2a are the same as those of the construction joint fitting in the first embodiment.
[0066]
As described above, the construction joint metal fitting using the round bridge can simplify the processing of the joint of the splint member (such as the flat joint 73) without using the main tree member such as a corner bundle. The processing time can be shortened, and the bonding strength between the metal fitting body 1 and the splint member can be increased.
[0067]
In addition, since the building joint using a round bridge can be easily joined, it is possible to improve work efficiency and safety even in a construction site where the scaffolding is high and the scaffolding is poor.
Further, the roof frame assembly can be performed without using the corner bundle 70, the baker 75, and the baker receiver 77 (see FIG. 5), and the cost of building materials can be reduced.
In addition, by using the building joints with round bridges, as shown in FIG. 13, there is no corner bundle 70, wall 75, corner wall receiving 77, etc., so the attic space is effectively utilized. can do.
[0068]
Next, a roof assembling method using the building joint fitting of this embodiment will be described with reference to the drawings.
FIG. 13: has shown the schematic perspective view of the principal part which shows the hut assembly of the dormitory roof using the joining bracket for construction of 2nd embodiment of this invention.
In the figure, the metal fitting body 1 is joined to a purlin 71, a corner joint 72, a flat joint 73, and a wife joint 74, and a round bridge 201 is connected to a corner joint 72, a flat joint 73, and a joint bolt 223. It is connected with wife Gassho 74.
The round bridge 201 is connected to a different round bridge or angle bridge described later via a connecting bolt 223.
[0069]
In the roof assembling method, first, the round bridge 201 and the metal fitting body 1 are connected by a fishing shaft bolt 216, a pipe sleeve 217 and a nut 218.
[0070]
Next, in this embodiment, since there is no corner bundle that is a main tree member provided vertically, a round bridge 201 that is provided with a temporary support (not shown) instead and is connected to the metal fitting body 1 on the temporary support. Are temporarily fixed, and the purlin 71, the corner joint 72, the flat joint 73 and the wife joint 74 are joined to the metal fitting body 1.
[0071]
Next, the block 205 of the anchor block 202 joined to each joint 72, 73 and 74 is rotated so that the connection bolt hole 251 is parallel to each joint, and the connection bolt 223 is inserted into the connection bolt hole 251. The tip of the connecting bolt 223 is inserted into the connecting bolt hole 214 of the round bridge 201 while rotating the block 251 in the horizontal direction, and the nut 224 is screwed. Needless to say, the nut 224 may be double-tightened to prevent loosening.
Furthermore, as shown to Fig.14 (a), when the distance L between the round bridges 201 provided in the both ends of the dormitory roof is short, the round bridges 201 are connected with the connection bolt 223. FIG. The distance L varies depending on the size of the entire roof, but is usually within about 1 m.
[0072]
In the construction fitting, the external force acting on the round bridge 201 by the flat joint 73 through the anchor block 202 and the connecting bolt 223 is almost canceled by the same external force of the flat joint 73 facing the flat joint 73. Further, by connecting the round bridges 201 as described above, the corner joint 72 and the wife joint 74 joined to one side of the roof are similarly opposed to the external force acting on the round bridge 201. Since it can be almost offset by the external force generated by the corner joint 72 and the wife joint 74, it is possible to provide a construction joint having a simplified structure and excellent mechanical strength.
[0073]
By the way, when the dormitory roof becomes long as shown in FIG. 14B, the structure in which the round bridges 201 on both sides are directly connected only by the connecting bolts 223 reduces the workability of the roof assembling work, Therefore, the angle bridge 206 may be provided between the opposing round bridges, and the round bridge 201 and the angle bridge 206 may be connected by the connecting bolt 223.
Next, the architectural joint fitting of the third embodiment using the angle bridge 206 will be described with reference to the drawings.
[0074]

As shown in FIG. 16, the angle bridge 206 has a structure in which a bottomed cylindrical body is vertically raised having an opening 261 on a rectangular bottom surface, and a mounting hole 262 is formed on the top surface. In addition, a connecting bolt hole 263 is formed in the side surface.
Further, the angle bridge 206 can be reduced in weight by forming a rectangular opening 261 on the back surface (the bottom surface of the bottomed cylindrical body), and is usually manufactured by welding a metal plate. The shape of the member to be welded can be simplified, and the manufacturing cost can be reduced.
[0076]
The angle bridge 206 is attached to the purlin 71 by the joining tenon 203, the pin 231 and the bolt 232, and the connecting bolt 223 is inserted into the connecting bolt hole 263, and the tip of the connecting bolt is connected to the connecting bolt hole of the round bridge 201. It is inserted into 213 and screwed with a nut 224.
In addition, the other structure and effect | action are the same as that of the joint fitting for construction of 2nd embodiment.
[0077]
In this way, even when the distance between the two round bridges 201 is long, the round bridge 201 can be firmly connected and attached to the metal fitting body 1, so that the metal fitting body 1 and the splint member can be attached. And the bonding strength can be increased.
[0078]
Further, when the dormitory roof is further lengthened, a plurality of angle bridges 206 may be disposed between the round bridges 201, and the angle bridges 206 may be connected to each other by the connecting bolts 223 and the nuts 224. Even if the dormitory roof becomes long, it is possible to provide a construction joint metal fitting that does not lower the joint workability and joint strength.
Although it depends on the overall size of the roof, normally, when the distance L is about 1 m to 2 m, one angle bridge 206 is provided, and when the distance L is about 2 m or more, two or more angle bridges 206 are provided. ing.
[0079]
In addition, although the joining metal fitting for construction of each embodiment of the present invention explained the case where the purlin 71 which is a splint member, the corner joint 72, the flat joint 73, and the wife joint 74 are joined in the dormitory roof of a Western style hut. The splint member is not limited to the above-mentioned wooden member used for the dormitory roof.
[0080]
Further, the present invention is not limited to a construction fitting, and the anchor block 202 is effective as a construction fitting even if it is not used together with the fitting body 1 or the round bridge 201.
Next, an embodiment of the anchor block will be described with reference to the drawings.
[0081]
